摘要: State-to-state time-dependent quantum dynamics calculations have been carried out to study ${\rm H}+{\rm DH}^{\prime} \rightarrow {\rm HH}^{\prime}+{\rm D/HD}+{\rm H}^{\prime}$ reactions on BKMP2 surface. The total integral cross sections of both reactions are in good agreement with earlier theoretical and experimental results, moreover the rotational state-resolved reaction cross sections of ${\rm H}+{\rm DH}^{\prime} \rightarrow {\rm HH}^{\prime}+{\rm D}$ at collision energy $E_{\rm C} =0.5$ eV are closer to the experimental values than the ones calculated by Chao et al. [J. Chem. Phys. 117 8341 (2002)], which proves the higher precision of the quantum calculation in this work. In addition, the state-to-state dynamics of ${\rm H}+{\rm DH}^{\prime} \rightarrow {\rm HD}^{\prime}+{\rm H}$ reaction channel have been discussed in detail, and the differences of the micro-mechanism of the two reaction channels have been revealed and analyzed clearly.
